How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security11
- TLS check failed: the certificate doesn't match the endpoint's hostname. See how to fix → View diagnostics → Fail
- Authorisation not yet verified: we couldn't confirm whether this endpoint requires it. View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS not yet verified: we couldn't read the response headers to check for it. View diagnostics → Unverified
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability0
- Transport check failed: declared streamable-http, but the TLS certificate failed verification. See how to fix → View diagnostics → Fail

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

How do I install the Protocol Career MCP server?
Protocol Career is a hosted endpoint at https://protocol-club.com/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the Protocol Career MCP server?
Protocol Career is an MCP server listed in the public MCP registry as io.github.Holox76000/protocol-career. Practice consulting drills and prepare for case interviews at the top US consulting firms. This page covers its hosted endpoint (https://protocol-club.com/api/mcp).
Does the Protocol Career MCP server require authentication?
Its publisher declares no required credentials for Protocol Career. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.
Is the Protocol Career MCP server still maintained?
Protocol Career is still listed in the MCP registry, though our most recent checks did not reach this channel. We last reached this channel on 19 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
